METALLIC CAR DOOR.

Application filed November 5, 1925. Serial No. 67,177.

This invention relates to improvements in metallic car doors.

An object of the invention is to provide a fabricated car door structuremade up of 5 sheet metal, having a re-enforced body and edge arrangementaffording great strength, durability and simplicity in construction,this application being a continuation in part of my prior application,Serial Number 486,808, filed May 8, 1919, now Patent 1,560,- 526,granted November 10,1925. 1

More specifically, the purpose of the invention contemplated herein, isto provide a metallic door made up of a plurality of sheet metal panelsprovided with strengthening corrugations, together with re-enforcingedge members in the form of rolled sections of angular formation, inwhich one angular portion is secured to the sheet metal panels in aparticular manner, said rolled section at the rear edge of the doorco-operating with means upon the anels to provide a spark seal, and theangu ar section at the bottom of the door-being arranged so as toprovide one angular portion which may be secured to the panels and whichincludes another angular portion disposed at right angles to the mainplane of the door and arranged to present an eflicient bearing memberfor supporting the door from the bottom formovement with respect tosupporting mountings usually rovided therefor.

Other and further ob ects of the invention will more clearly appear fromthe description and claims hereinafter following.

In'the drawings, Figure 1 is a front, elevational view of a car door,made up in accordance with my invention; Figure 2 is a vertical,sectional view of the door substantially on the line 2-2 of Figure 1,with fragmentary views of supporting rollers showing the adaptability ofthe bottom edge of the door for co-operation with the supportingrollers. Figure 3 is a horizontal, sectional .view of the doorconstruction substantially on the line 3-3 of Figure l. Figure 4 is avertical, sectional view similar to Figure 2, showing a slightlydifferent embodiment of the invention; Figure 5 is a,

horizontal, sectional view similar to Fi ure 3, showing the constructionillustrate in Figure 4. Figure 6 is a front, elevational view similar toFigure 1, of a slightly dif ferent embodiment of the invention. Figure 7is a vertical, sectional view of the door substantially on the line 7'7of Figure 6. And Figure 8 is a horizontal, sectional View of the doorconstruction on the line 88 of Figure. 6.

Referring first to Figures 1 to 3, inclusive, the invention contemplatesthe provision of a metallic door of the usual rectangular form,

and which includes a main body portion made up of a plurality,ofmetallic sheet metal panels 10, 11 and 12, said panels havmg theiradjacent horizontal edges overlapped and rigidly connected by welding orby rivets, as indicated at 13. Each of the panels is made of relativelythin sheet metal, and in order to reduce its thickness to a minimumconsistent with the necessary strength, each panel is provided withstrengthening means, in this instance being shown as horizontallydisposed corrugations 14 and adjacent the forward and rear edges of themain body portidn, the panels'are pro- Vided with vertically disposedcorrugations 14 and 15, the material of the body portion extendingoutwardly of the corrugations 14 and 15 to provide marginal sections 16and 17, the main body portion also extending outwardly of the uppermostcorrugation 18 and the lowermost corrugation 19 to provide marginalsections 20 and 21. The vertical corrugations 14 and 15 at their upperand lower extremities preferably merge with the upper and lowermosthorizontal corrugations 18 and 19, and the remainder of the horizontalcorrugations 14 preferably merge with the vertical corrugations 14 and15, as shown. The rear top and bottom marginal portions 16, 20 and 21 ofthe main body portionfare flanged in each instance, as indicated at 22,each flange extending inwardly at an angle to the main plane of the doorand beyond the inner face thereof, the flange atthe rear edge of thedoor in conjunction with a reenforcing element hereinafter referred to,being arranged to operate as a spark seaL Associated with the bottomedge of the main body portion is a combined reenforcing element andsupporting member 22, which in this instance takes the form of aninverted T bar, the vertical flange 23 of which is secured to themarginal section 21 of the main body. portion by welding, or by rivets,as indicated at 23. The flange 24 at the 1nner side of the centralflange or stem 23 of the T section, extends beneath the in-turned flangeindicated at 22 at the bottom of the door, and lies against the same.The opposite flange 25 extends outwardly substantially at right anglesto the main plane of the body portion and forms part of the lowermostportion of the door, and provides a horizontally extended member adaptedto bear upon suitable mounting means such as rollers to support the doorfrom the bottom for operating movement.

The marginal portion 16 at the rear edge of the door likewise has a Tsection 26 associated therewith, the stem 27 of said T section beingsecured to the marginal portion by welding, or by rivets, as indicatedat 28, the flange 29 at one side of the stem extending outwardlysubstantially at right angles to the main plane of the body portion, andthe opposite flange 30 extending inwardly beyond the inner face of thedoor and lying against the turned flange 22 on the main body portion,the flange 30 and the flange on the body portion co-operating with theusual means associated with the door mountings to form a re-enforcedspark seal. The top edge of the door has a T section 31 associatedtherewith, and the stem of the T section is connected to the marginalportion 20, the flanges of the T section extending to opposite sides ofthe main body portion in the same manner heretofore described withrespect to the bottom and rear edges. The forward edge of the door hasan angular member 32 associated therewith, one flange 33 being securedto the outer face of the marginal section 17 and the other flange 34extending outwardly substantially V at right angles tothe main plane ofthe door. The members 22, 26, 31 and 32 are connected at their meetingends by any suitable means to provide a continuous frame. As beforestated, the T section at the bottom of the door serves as a member forsupporting the door from its bottom edge upon rollers, such as thoseindicated at 35, although it is apparent that other means may beutilized adapted to engage-the T section at the bottom of the door tosupport the same for its operative movements.-

Referring now to Figures 4 and 5, there-is shown a construction which,so far as the main body portion and the T bars are concerned, isidentical with that heretofore described, and consequently the samereference characters will be used to designate similar parts in the twoconstructions, except where otherwise indicated. In conjunction with adoor of the character described in connection with Figures 4 and 5,re-enforcing strips are disposed on the inner side of the door andadapted to brace the same in a novel manner. In this connection a strip36 is shown at the rear edge of the door, which strip is verticallydisposed and has its inner edge secured to the body portion of the doorinwardly of the corrugation thereof,- being secured by welding, or byrivets, as indicated at 37, the strip bridging or spanning the mouth ofthe corrugation and having its outer end 38 connected to the marginalsec-- tion disposed outwardly of the corrugation.

The top, bottom and forward edges of the door are provided withre-enforcing strips in identically the same manner, each of l whichspans the related corrugation and has Referring now to Figures 6 to 8,inclusive, so

there is shown still another embodiment of the invention. In thisconstruction sheet metal panels 40, 41 and 42 are shown having theiradjacent horizontal edges over-lapped and rigidly connected by welding,or rivets,

as indicated at 43, to provide a continuous rectangular body portion.The forward rear, top and bottom edges of the body portion are providedwith reenforcing means of identically similar character, and in this .90

connection it is deemed sufficient to describe the construction at oneedge portion and use similar reference characters, to designate similarparts of the remaining edge'portions of the main body portion. At thebottom 05 edge of the door, the main body portion is provided with aninte ral portion 44 inclined outwardly from t e main plane of the door,the integral portion 44 having thereon an integral extension orcontinuation 45 which extends substantially parallel with the main planeof the'door, and outwardly of said parallel portion, the extension 45 isturned inwardly toward the main plane of the door, as indicated at 46.Secured to the inner face of the main body portion inwardly of theinclined portion 44, by means of welding, or rivets, as indicated at 47is a re-enforcing strip 48, which extends outwardly of the angularportion. 44 and exten- 11 sion 45 is spaced relation with respectthereto, and extends outwardly beyond the turned portion 46 on theextension 45. Associated with the re-enforcing strip 48 and the lowerend of the main body portion, is a re-enforc-' us ing section 49, which,as shown, is in the form of an angle bar havin one flange 50 extendingsubstantially at rigIit angles to the main plane of the door, whichflange is secured by suitable means, such as welding, or

rivets, to the turned portion 46 on the extension 45, and the other flane 51 of said angle bar extending parallel wit the re enforcing strip48', and being secured thereto by suitable means, such as welding, orriveting. It

will be noted that the flange 50 of the angle bar rovides a horizontallydisposed bearing mem e r adapted to 00-0 erate with suitable mountingssuch as the ro lers 52 for supporting the door from its bottom foroperative movement. As above stated, the construction at the front, topand forward edges of the door is identically similar to that abovedescribed, the angle members being connected together by suitable meansto provide a frame. Inwardly of the angularly disposed portions 44 ofthe door, the'main bo'd portion is provided with a plurality ofhorizontally disposed corrugations 53, said corrugations preferablymerging at the forward and rear edges of the door with the hollowtube-like formation provided by the an ular portions, re-enforcing stripand assoclated angle bar.

While I have herein shown the preferred manner of carrying out theinvention, the same is merely illustrative, and I contemplate allchanges and modifications which come within the scope of the claimsappended hereto.

I claim:

1. In a car door, the combination with a metallic body member; of are-enforced edge construction for said body member, comprising anintegral angular portion of said main body member turned outwardly ofthe face of the door away from the main plane of said door, saidintegral portion having an integral extension extending at an angle tothe angular portion and outwardly toward the edge of the door; are-enforoing strip having its inn/er edge secured to the main bodymember inwardly of said angular portion and extending toward the ed e ofsaid door in spaced relation with .re erence to said angular ortion andextension; and ansubstantially at right angles thereto, sai

angular member being secured to said extension and to said strip andco-operating therewith to provide a hollow tubular formation.

2. In a car door, the combination with a main body portion composed ofsheet metal and having a corrugation extending along one edge thereofwith a fiat marginal portion outwardly of said corrugation; of means forreinforcing said edge of the door in the form of a T-section having thestem thereof secured to said fiat marginal ortion and with the flangesextendin inwardly and outward- 1y of the stem, and a strip secured tothe main sheet body portion at points inwardly and outwardly of saidcorrugation and bridging the 0 en mouth thereof.

In witness t at I claim the foregoing I,
